Ok scenario time... I am looking to buy one for a tiberius 9.1 marker and i do like the idea of it mounting under the barrel area, except it takes up all the room and rumor has it that I cant put a grip down there after i add the qloader system. Would the system be strong enough to kind of use it as a grip itself? Still in the same horizontally aligned with the barrel.

i play with one underbarrel, and while i wouldnt put any extreme stress on it, i hold it in my hand to help support it. So you should be fine there.

This.

Overall, the socket is fairly sturdy, but at the end of the day it's still plastic. That said, I've never been afraid of making a move (other than diving, but for much different reasons) for fear of breaking the Q.
